GLOVE-TIPPING MACHINE.

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed May 25. 1906. Serial No. 318.623.

TO all whom it may concern:

Be it known that we, ALBERT M. BANKER, residing at J ohnstown, and FRANK OUKTIN, residing at Gloversville, in the county of Fulton and State of New York, .have invented certain new and useful Improvements in GloVe-Tipping Machines, of which the fol- V lowing is a specification.

The invention relates to such improve- ,ments and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures therein.

F igure 1 of the drawings is a view in side elevation of our improved glove-tipping machine. Fig. 2 is a plan View of the under side of the work-plate detached. Fig. 3 is a view in front elevation of the machine, with the work-plate removed. Fig. 4 is a vertical, longitudinal section of the same taken on the broken line 4-4 in Fig. b. Fig. 5 is a top plan View of the machine with the work-plate removed, and the head broken away, and certain parts shown in horizontal section. Fig. 6 is a Vertieal cross section of the same taken on the broken line 6 6 in Fig. 5, viewed in the direction of the arrow. Fig. 7 is a view in real' elevation of the machine.

,In the manufacture of certain kinds of gloves, particularly ladies silk and cotton gloves, it is customary to reinforce the ends of certain of the fingers where most exposed to wear. This is commonly accomplished by making the finger, at the point where it is desired to reinforce the same, of double thicknesses of fabric by applying and securing tothe inner side thereof a reinforce-piece or tip Which may be either integral with, or separate from, the finger-Strip itself, said tip being stitched to the body of the tiiger-strip. The operation of thus stitching the reinforeetips to the bodies of the finger-strips is accomplished while the glove is yet in blank form and as a prelirninary operation to the forma tion of the finger-sheaths. The inner end of the tip which extends transversely of the finger-sheath is preferably secured to the finger- Strip by an over-seaming operation termed blind stitching whereby the seaning thread is confined Wholly to the side of the fingerstrip to which the tip is attached, and does not appear upon the outer side of the Strip which is exposed to view when the glove is worn. As a desirable mode of procedure to aceomplish the stitching of the rein'force-tips to the 'finger-bodies in this manner, the finger portions of the gloVe-blank are folded over the edge of a thin metal plate at about'the point where the stitching is to be inserted, with the tips applied to the folded-over portions of the 'finger-bodies, the inner edge of each tip being eXposed adjacent to the foldline of its finger-strip ust beyond the edge of said plate, in. which position the parts are held by spring-clamps while the bla-nk thus mounted upon said plate is fed to a sewing machine which perforlns the stitching operation.

The present invention relates in certain of its features to machines for thus stitcling the reinforce-tips to the 'linger-strips, and in certain other features to the construction of the work plate for supporting' the blanks in proper position for presentation to the stitch- 'forming mechanism.

Certain objects of the invention are to present the work in a horizontal position to the stitch fm'ning mechanism the needle of which operates in a vertical plano; to avoid danger of entanglement of the work with the operating mechanism; to secure by suitable adjustment greater accuracy in the insertion of the stitches; and to facilitate the work of the operator.

Other objects of the invention will appear in connection 'with the 'following description.

Referring to the drawings wherein the invention is Shown in its preferred form, 1, represents the base, 2 the arm, and 3, the head of an Ordinary form of sewing machine, employing 'a needle, 4, operating in a vertical plano, and a looper, 5, all of which may be of the Usual :form adapted 'for making an over-edge seam, using' a single thread.

The machine is provided with a pair of disks, 6 and 7, between which thework is adapted to pass in a horizontal position to the stitchformiiig' mechanism. The upper disk, 7, is rotatively mounted upon the offset end of an arm, 8, pro jecting from the spindle, 9, rotatively mounted in the head of the niachine, whereby the disk, 7, is adapted to be swung into and out of 'position to coperate with the lower disk 6. The lower disk is rotatively mounted upon a stud, 15, projecting transversely of the path of the work from the rocker-arm, 10, fiXed upon the rock- Shaft, 11, supported in bearings vat the side of the machine, said. rocker-arm eXtending transversely of the machine, below, and in rear of, the'needle, and parallel with the line of movement of the work, The disk, 6, is undercut on its rear side to form a space adapted to receive the throat-plate, 12, which occupies a vertical position, and is provided on its real' side with a vertical groove to receive the needle. The throatplate is secured in position by means of an L-shaped base, '13, attached by means of screws, 14, to the upper side of the rockerarm 10. The rOcker-arm, 10, is yieldingly forced upwardly by means of a plate-Spring, 16, the force of which is regulated by means of a set-screw, 17, the position of the rockerarm being determined normally by means of a set-screw, 18, inserted downwardly through the bed-plate of the machine in the path of a lug, 20, projecting rearwardly from the rocker-arm. By means of said set-screw, 18, the normal vertical position of the disk, 6, and throat-plate, 12, can be accurately regulated. The disk, 6, and throat-plate can be depressed when desired by means of an angle-lever, 21, Which may be operated in any known manner, one arm of said level' Overhanging the Swinging end of the rockerarm 10.

The Work to be fed to the machine is mounted upon a work-plate, 22, Which is supported in a horiZontal position with its inner edge interposed between the disks, 6 and 7, resting upon the former. The workplate, 22, is provided on its underside with a series of Spring clamps, 23, operating in the usual manner to clamp against the underside of the plate the folded-over end-portions of the finger-strips, with the reinforce-tips applied in proper position thereto, while the body of the fiiger-s-trips and hand-portion of the glove are drawn over upon the upper surface of the work-plate into engagement with the retaining pins, 24, Which serve to hold the finger-strips stretched over the edge of the plate in position to receive the over-seam stitches inserted by the stitchforming mechanism. The work-plate, eX- cept for the pins, 24, presents a smooth, flat, upper surface upon which the work Can rest free from danger of entanglement with the operating mechanisms. At or near its outer end', the work-plate, 22, is pivotally mounted at, 25, 'upon a slide, 26, the aXis of the pivotal connection extending in a horiZontal line parallel with the line of movement of the work. The slide, 26, is located beneath the work-plate and is adapted to fit and slide longitudinally along a slideway, 27, formed ln an adjustable bed, 28, on the front end of the machine. The outer wall of the slideway ls formed by a Separate plate, 70, beveled or chamfered on its inner Side to form an up- Wardly fiaring slideway, which plate rests upon Supporting screws, 71, by adjustment of which it can be lowered and raised to take up any lost motion due to Wear, said plate being locked in adjusted position by means of the screws, 72, which pass through the respective slotted apertures, 73, in Said plate. The adjustable bed, 28, is moved along slideways, 29, on the main frame of the machine toward and from the vertical line of the needle, being secured to said main frame by means of screws, 30, inserted through slots, 31, in the inwardly projecting legs, 32 Which form a part of said adjustable bed. The location of the adjustable bed can be accurately determined by means of three adjusting screws, One of which 35, passes loosely through an aperture in a fiange, 34, depending from said adjustable bed and into a screwthreaded aperture in the main frame of the machine whereby it is adapted when screwed inwardly to force the adjustable bed inwardly along its slideways, 29, the other adjusting screws, 33, 33, passing through screwthreaded apertures in said depending fiange, 34, into engagement with the main frame of the machine and being adapted when screwed inwardly to force the adjustable bed outwardly. By this means the bed can be accurately adjusted and maintained in adjusted position, being further secured, When adjusted, by tightening the screWs 30. It is thus possible to secure an eXtremely accurate adjustlnent of the Work-plate to cause the inner end of the same to properlycoperate with the stitch-forming mechanism, which is very desirable as the formation of blind stitches by means of a sewing machine requires that the position of the work should be adjusted to the position of the needle within the dimension of a thickness of the fabric in order that the stitch may neither show through the fabric nor entirely skip the fabric of the finger-Strip.

Siide movemcnts may be imparted to the slide, 26, and work-plate in any known manner. As a preferred means for imparting to the Work-plate a step-by-step movement I have shovn the work-plate-slide provided on .Its under side v ith gear-teeth, 36, forming a gear-rack adapted to be engaged by a gear- Wheel, 37, rotatively mounted upon a stud, 38, 'liXed upon the adjusta le bed, 28, the engagement of said gear with said gear-raek being permitted by means of an opening in the bottom of the slideway 27. The gear 37, is fixed upon a slceve, 39, upon which is also fiXed a ratchet, 40, adapted 'to be engaged by a pasi, 4], on the upper end of a lever, 42, fulcrumed at, 43, upon the adjustable bed, 28, and having its lower end provided with a follovv'er, 44, adapted to be engaged by,a cam-Segment, 45, fiXed upon a rook-shaft, 46, eXtending longitudinally of the machine from the front end of the machine to the rear end thereof whereat it has iXed thereon a rockerarm, 47, connected hy pitman, 48, with an eccentric, 49, onthe main shaft, 50, of the machine. The follower, 44, is held against the cam, 45, by means of a coil-spring, 5], connecting the lower arm of the lever, 42, with a fiXed Support on the adj ustahle hed 28. AS the machine operates, a roeking movement is imparted to the roek-Shaft, 46, through the eceentric, 49, and pitman, 48, which rocking movement is im parted through the cam, 45, and follower, 44, to the lever, 42, eausing in connection with the Spring, 51, a reciprocating movement of said lever and pawl, 4], and a s'tep by-ste) movement of ratcliet, 40, connected gear-wlieel, 37, and work-plate 22. Aecidental movement of the ratchet, 40, and gear, 37, is prevented hy engagement Mith the sleeve or hul) upon Which they are monnted ol' a frietion-platm 74, adapted to be forced against said hul) or sleeve with the desired degree of force hy means of a set-serew 75. The eam, 4:"), is adj ustahly seeured to the rock-shaft, 46, hy a set-screw, 52, permitting the cam to he properly adjusted when the adjustahle hed has been adjusted to the desired position.

On Opposite sides of the lower disk, 6, are provided stationary slideway-supports, 60. along Which the inner edge of the w ork-platc slides in approaehing and leaving the disk. The top of these slidew ay supports is approximately tangential to the top of the lo er disk, but the pivotal Connection between the Work-plate and its slide, 26, permits a reeking movement of the work-plato upon smh. pivotal connection to adapt its inner end to any desired variation in height in passing through the machine, as well as leaves its inner end under the control, as to height, of the disk 6. As a means for aecurately locating the throat-plate and lower disk, 6, relatively to the needle, we have shown means for adj Listing longitndinally the rockshaft, 11, which pas'ses through hearings at, 61 and 62, at the side of the machine. 'l'he bearing, 62 is shown in the form of an interiorly scre'fv -threaded split-hearing, the members of uhith are adapted to he elamped tightly upon a bearing sleeve, 63, whieh is similnl exteriorlv serew-thi'enled. A rednced end of the reck-shaft, 11, fits i'thin the sleeve, 63, vithin \khi h it is eapaile of rotative movement w hile longitudinal movement is prevented hy means of a rollar, 64, whieh is fixed upon the larger portion of said shaft in position to engage one end of the hearing sleeve, 63, and a mit, 65, litting the Screw-threaded outer end of said shaft, 11, and adapted to alut upon the oppesiie end of said bearing sleeve 63. \When the scre 66, Whieh serves to draw together the memhers of the split bearing, 62, is loosened, the hearing sleeve, 63, can he rotater'l within the hearing, 62, by means of a spanner or key adapted to lit the socket, 67, formed in a peripheral flange on said sleeve, Said rotative movement serving, hy reason of the screwthreaded connection hetween the sleevc and hearing, 62, to cause a longitudinal movement of the sleeve accompanied hy a like movement of the rock-shaft H. ll hen the desired adj ustment has heen aeeomplished the bearing sleeve is locked in position hy tightening the serew 66.

ln the operation of the machine a plurality of work-plates 'will he employed, it only hemg necessary for the operator to clamp the work 'roperly upon a work-plate and insert the same in the maxhine, after whieh the operation proeeeds automatieally, the pla'te and work passing out of the machine at the side Oppo ite ,that at whieh they entered it, leaving the operator free to prepare another plate during the passage of the previouslv prepared plate through the maehine.
